FIRING METAL CLAY
Drying Time
Allow your pieces to be completely dried before firing them in the kiln to ensure that they
don‟t warp.
Loading the kiln
If you fire both glass and metal clay in your kiln, it is
recommended that you invest in a second shelf so that you
can fire only glass on the glass kiln shelf, and only metal
clay silver on the other kiln shelf. After firing your PMC
piece, some of the metal particulates impregnate the kiln
shelf and leave stains on the shelf‟s surface. If you fire
glass on the very same shelf, there is a chance that glass
and metal may have a reaction that will result in silver
stains left permanently on the glass.
Pieces that have a flat side can be placed directly onto the
kiln shelf. They can be positioned closely together, but
they shouldn‟t touch.
Pieces that are rounded, hollow or very delicate in composition will need support while
firing so they don‟t collapse. Pour alumina hydrate or vermiculite into an unglazed
ceramic bisque bowl and carefully place the metal clay pieces onto the alumina
hydrate/vermiculite. Again, they can be positioned closely together, but they shouldn‟t
touch.
FIRING THE KILN
Begin in the IDLE mode
To begin programming the kiln, it must be in the IdLE mode. This can be determined by
viewing the LED display. The display will alternately display both the current
temperature and the IdLE message. When the kiln controller is first turned on, it will
display the current firing configuration that it is in.
Press (Program) button to return to the IdLE mode.
Select the firing configuration
To determine the current firing configuration
Press (Increase) button and hold until the LED display shows CFG
Press (Program) button to display the current firing configuration.
